Conjunto Primavera

This madly prolific norteno powerhouse came out of Chihuahua, Mexico in 1978 and has become something of an institution in the regional music world ever since. Founded by saxophonist Juan Dominguez, the group broke into public consciousness in early '80s with songs like "Amigo Mesero" and stayed there thanks to a talent for keeping their sound -- which they've described as grupero/norteno fusion -- fresh. But the group didn't achieve true superstar status until 1998, when hits like "Perdoname Mi Amor" and "Necessito Decirte" colonized the charts and made them staples of the airwaves. The group also has a heart: they're known for charitable work that includes donating money to aid children with cancer and building a school and a breakfast cafeteria in their home state.
